Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.
What property of radioactive elements make them useful for determining absolute age?
The property of radioactive decay is what makes radioactive elements useful for determining absolute age. By measuring the amount of parent and daughter isotopes in a sample, scientists can calculate the age of the material based on the known half-life of the radioactive element.
What property of radioactive elements make useful for determining absolute age?
Igneous rock. If you are in FIS you know me. O.K.
Why can't chemical treatment be used to destroy the radioactive products produced in a nuclear reactor?
The radioactive materials produced in a nuclear reactor are radioactive because of instability in the nucleus of the atoms of the radioactive materials. Chemistry only affects the way elements behave because of the electron structure. Chemistry is electonic and the radioactive products have problems in their nuclei. Chemistry doesn't affect the nucleus of the atom, so chemical methods cannot be used to deal with radioactive materials, per se.
How does something become radioactive?
An element becomes radioactive when its nucleus is unstable and undergoes radioactive decay, emitting radiation in the form of alpha, beta, or gamma particles. This process occurs naturally for some elements or can be induced through nuclear reactions in a laboratory setting.
Can plutonium mix ti make another element?
- Plutonium can react with other elements to form chemical compounds- Plutonium can be transformed in other elements by nuclear reactions or radioactive decay
What are the unique properties of actinide metals?
Actinide metals have unique properties including high density, high melting points, and the ability to exhibit multiple oxidation states. They are also radioactive and can undergo fission, making them important for nuclear power generation and weapons production. Additionally, actinides have a variety of magnetic and electronic properties that make them useful in various technological applications.
Are the elements that make up the iron triad radioactive or are they magnetic or are they alkali metals or are they alkaline earth metals?
There transition, which is the same thing as magnetic
What is Prefix of behave?
mis- can be added to behave to make "misbehave."
Why is uranium radioactive?
Positives repel each other. In an atom, the nucleas is full repelling protons with their positive charge. It is the nuclear force that holds them together in the nucleus. A Helium atom has only 2 protons which makes it more stable.Uranium on the other hand, has 92 protons all squashed together. This makes it very unstable which allows it to undergo gamma radiation.That is why Uranium is radioactive.Unstable atoms as uranium are radioactive; the stability depends on the ratio between protons and neutrons.
What is the heaviest radioactive element?
Polonium is often considered to be the most radioactive element, but there are far more radioactive elements like nobelium and lawrencium. However, the most radioactive elements are man-made like ununtrium and ununseptium. Out of these, ununoctium is the most radioactive but scientists are continuing to make even more radioactive elements today.
